Hall Effect in Excitonic Insulator

概要
- 論文の詳細を見る
The Hall effect in a weak magnetic field of an excitonic insulator in the semimetallic limit is investigated by the use of the Green function formalism developed recently. Correlations between electrons are treated under the Hartree-Fock approximation with only a dominant term and the effect of impurity scattering is considered. The Hall coefficient increases as the temperature is lowered near T=0, reflecting the reduction of the number of effective charge carriers; it diverges in a pure case and remains at a finite value in a dirty case. Near T_c it deviates from the normal state value linearly with T_c-T and, in a pure case, it shows a minimum.
